LINE-THROVVING PROJ ECTILE.

SPECIFICATION forming part of Letters Patent No. 310,852, dated January 13, 1885.

Application filed May 5, 158i.

T0 all whom it may concern:

Be it known that I, PHILANDER B. Roys, of Pultneyville, in the county of Vayne and State of New York, have invented a new and useful Improvement in Continuous Line- Throwing Projectiles; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is a continuous projectile for life-saving service, and for like purposes. It is intended to be used as a projectile for throwing a line from ship to shore, or the reverse, or from ship to a person overboard, or from one ship to another, or a lifepreserver to a person overboard.

In the accompanying drawings, Figure l shows a central longitudinal section of the projectile. Figs. 2, 8, 4, and 5 represent the parts of which it is composed detachable from each other. Fig. 6 represents the stand from which the projectile is fired. Fig. 7 shows the head of the projectile, with a series of hooks pivoted thereto, forming a grapnel.

In these drawings, B represents the case or body ofthe projectile, this being a tube of any suitable metal, as iron or steel, and of alength required for the work which it is to perform. In it is placed most of the material, the coinbustion of which is to form the power by which the projectile is driven. A head, A, of conical or tapering form, and preferably of wood, is inserted into a threaded socket in the forward end of this tube to cover the cartridge ofthe projectile. Just in rear of this head is an air-chamber, G, for the purpose of giving buoyancy to the projectile and to cause it to float upon the water. In the remaining part of the case is placed an inside case (marked E) of paper or wood, or any suitable material adapted to hold the combustible ingredients which are to form the gases and to keep them dry under all circumstances. The butt of the case (marked G) is externally screw-threaded, as shown at F, and upon this is screwed a supplemental case having an interior thread. This supplemental case is made of malleable iron or brass, and the bottom of it is funnelshaped,as shown at H. It communicates with a hollow nipple, h, which projects axially to the rear, and is provided with a cap,7.,adapted (No model.)

to fit over it and make a water-tight joint. The rear end of the supplemental case is screwthreaded to receive a plug. K, in which are set the ends of a prolonged wire loop, I, to which the line is attached by means of a snap-hook, L rIhe case E, which contains the gas-producing ingredients, is preferably made with a conical end and hollow nipple adapted to fit the conical seat of .the outer case, G. A cap, J, Fig. 5, is provided also, to cover the rear end of the case G and preserve the ingredients from moisture, which may be made of brass or rubber. rlhehollow nipple or tube It forms an extended escape for the gases, and serves to increase the power as well as to direct the course of the projectile, and the extended loop forms a line-traveler on which the line moves as the projectiles start.

Vhen the projectile is red from the shoulder, I may use any desired form of support; but ordinarily the supporting-frame shownin Fig. 6 will be used. This consists of a slotted forward support, l, hinged to a rear support, 2, these being mounted upon legs 3. An extensiblc brace, 4, supports the forward hinged extension upon the legs and allows the proper change in the elevation of the projectile. Braces 5 may be used to steady the support when it is in position. The projectile is laid upon the support, as shown in dotted lines in Fig. 6, andthe charge is ignited by a fuse, or in any convenient way. For this purpose a ha1nmer, 7, may be set upon the rear part of the supportingiramc.

The legs heretofore described may be made extensible, as shown in Fig. 6. A small standard, 8, pierced with a series of holes equally distant apart, serves as a frictionprimer for igniting the projectile when a cap is not used.

As shown in Fig. 7 I may provide a series of hooks for the shell of the head of the projectile, which may rest in slots therein, and so arranged as to be thrown outward after the projectile has been fired and landed, the sudden stoppage effecting this. These hooks form a grapnel and hold the projectile where it falls.

I claiml. In a projectile of the class described, the combination of the body B, provided with IOD suitable head, the independent case E, conrained within the case B, adapted to receive Vthe combustible material, the supplemental head A, the independent case E within the I case B', containing the combustible material,

constructed substantially as described,the supplei'nental casing G,adapted to the body B,and having,` the conical seat, and the hollow nipple h, all the parts being,` arranged and operating substantially as described.

In testimony whereof I have signednmy name to this specication in the presence of two subscribing witnesses.

PHILANDER B. BOYS.
